ContentWise Impressions

The ContentWise Impressions dataset is a collection of implicit interactions and impressions of movies and TV series from an Over-The-Top media service, which delivers its media contents over the Internet. The dataset is distinguished from other already available multimedia recommendation datasets by the availability of impressions, i.e., the recommendations shown to the user, its size, and by being open-source. The items in the dataset represent the multimedia content that the service provided to the users and are represented by an anonymized numerical identifier. The items refer to television and cinema products belonging to four mutually exclusive categories: movies, movies and clips in series, TV movies or shows, and episodes of TV series. The interactions represent the actions performed by users on items in the service and are associated with the timestamp when it occurred. Interactions contain the identifier of the impressions, except in those cases where the recommendations came from a row added by the service provider. The interactions are categorized in four different types: views, detail, ratings, and purchases. The impressions refer to the recommended items that were presented to the user and are identified by their series. Impressions consist of a numerical identifier, the list position on the screen, the length of the recommendation list, and an ordered list of recommended series identifiers, where the most relevant item is in the first position.
